To all whom it may concern Be it known that we, FREDERICK B. VAN VLEcKand GEORGE NICHOLS, of Plainfield, in the county of Union and State ofNew Jersey, have invented, made, and applied to use a certain new anduseful Improvementin Supporters for Window Sashes and Blinds; and we dohereby declare the following to be a full, clear, and exact descriptionof the said invention, reference being had to the annexed drawings,making part of this specification, wherein- Figure l is a viewrepresenting part of a sliding blind with our supporter attached, theparts being partially in section. Fig. 2 is a separate elevation of oursaid supporter; and Fig. 3 is a cross-section of the same.

The saine parts are denoted by corresponding letters.

Supporters for railroadcar windows and blinds have heretofore usuallybeen attached to 011e side, and a separate lifting-piece applied at thecenter of the window or blind, requiring the use of both hands inraising or lowering the same. I

The nature of our said invention consists in a sliding latch at the sideof the window or blind, connected with the thumb-piece or lifter at ornear the center of saidV sash or blind, whereby the supporter can beoperated by one hand in the act of raising or lowering the said windowor blind.

1n the drawings, a represents the sash, blind, or window; b, the casingin which the sanIe is tted to slide. c is a plate with the lifter d ator near the center of the said window or blind. e is the thumb-piece,passing through a mortise in c, and connected to one end of the bentlever j" upon the fulcruni i, and the other end of said lever j' isconnected with the latch g by a short link. This latch g is made with ascrew-stem, g', so that the length thereof Inay be adjusted toaccommodate any slight variation in vthe distance loetween the plate cand casing I), and the end of the said latch g slides in a plate, h,screwed to the edge of the sash or blind.

k is a spring acting between the support l for said bolt g and aprojection on said bolt, to keep the same projected except whenwithdrawn by pressing upon the thumb-piece e.

o o are notches in the casing to receive the end of the latch g.

It will be understood that the latch g passes through a hole bored infrom the edge of the win dow or blind, and that the screw-stem allowsthe latch g to be entered from the said edge and screwed into theconnection to the lever f.

If desired, the end of the lat-ch g may be made square, or nearly so, toenter a hole in the casin g and act as a bolt, and this bolt may alsoact as a latch in some ofthe notches o, if they are sufficiently deepand beveled in the direction shown in the drawings.

What we claim, and desire to secure by Letters Patent, is-

rIhe thumb-piece e, passing through a mortise in the plate c, andconnected to the bent lever f, in combination with the lifter d, bolt g,and spring 7c, the parts being arranged and acting as and for thepurposes set forth.

In witness whereof we have hereunto set our signatures this 27th day ofFebruary, A. 1).'1866.
